Why do we use a Double Walled Rim and heavy duty 36 Gauge Spokes? ? 
In the beginning we tried various kits and many of the brush less motors were very good motors. The problem with most of the conversion kits available are that they are spoked incorrectly, use a single walled weak rim., have spokes that are the wrong length causing the spokes to be bent in an "s" shape. Simply put bicycle wheels were not made for this type of torque on them and on occasion you will need to tighten your spokes until they finally "seat" themselves. 

FRONT wheel or  REAR wheel ? 
FRONT elctric bike kits= easy to install, easy to maintain. This is the best for 
Balance if you are using SLA batteries on a rear mounted rack because of 
The weight. 
REAR electric bike kits= harder to install, BUT for big motor, =More safety Installation only for the very 
Mechanically inclined or professional. Only enough space for 7 rear speeds 
Max (we ship with 5 speed). Bad balance if you are using heavy SLA 
Batteries...Good for wheelie's lol but bad and unsafe balance with SLA. 
Good points are that they are a slightly more natural feeling ride when using 
Lightweight LiFePO4 batteries
